Abstract
The invention relates to a fluid-driven clutch in which a non-rotatable clutch ring is axially slidable on a shaft via a fluid introduced into a pressure chamber for transmission of the driving force through a tooth system engaged with a corresponding clutch ring having a corresponding tooth system. The seals for sealing the pressure chamber are arranged in such a way that they are not permanently in contact with the wall of the pressure chamber to be sealed. This ensures that the seals do not impair the mobility of the axially lidable clutch ring.
